9:00 am - 9:30 am Conference Kick-Off: Your Industry Landscape

Listen to an OEM and T1 give their perspective on the current challenges and opportunities facing the suspension industry. Each presentation will last 10 minutes followed at the end by a 10 minute Q&A session.

The aim of this presentation is to improve low-frequency comfort, defined in the frequency range [0; 5] Hz, of a semi-active suspension system. To do, an analysis and synthesis approach is proposed on a functional scale. A target behaviour of the equivalent open-loop, seen from the angle of low-frequency comfort, is generalized using CRONE-SkyHook (CSH) and SkyHook approaches.

All simulations, in both frequency and time domains, are performed via AMESim and MATLAB/Simulink cosimulations using a full vehicle model incorporating the non linear characteristics of the suspension spring and damper. Simulation results show that requirements in terms of body handling under road solicitations and filtering are respected.
